B and E are true statements for the Oracle Exadata Configuration Assistant (OECA). OECA facilitates PDU power selection initially and after equipment addition, and it allows for the elastic configuration of the hardware. It does not reconfigure the size of disk groups or recreate grid disks, nor does it allow for a single XT storage server in the configuration. The "Add Equipment" input option does allow for the allocation of RU slots for customer equipment.

References for this information can be found in the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources.

Option 5 stops the clusterware on all database servers as the grid user3.

Option 8 shuts down all Exadata storage servers using their ILOM interfaces1.

Option 7 shuts down all database servers using their ILOM interfaces1.

Option 6 powers off the rack using the power switches on the PDUs2.

According to the Oracle Auto Service Request (ASR) documentation1, ASR raises service requests for qualified Oracle products that are detected with specific faults. The qualified Exadata products include2:

Database servers

Storage servers

InfiniBand switches

Cisco switches (X8M and later systems)

Power distribution units (PDUs)

According to Oracle’s documentation12, some of the statements that are true about applying updates on Exadata systems are:

Failed storage server updates are automatically rolled back to a previous release1.

When running a “yum update” for a new Exadata release, all other repositories should be disabled1.

Oracle Platinum Services provides patching features for the full software stack, which includes operating systems, virtualization, storage software and firmware, and databases. This service is typically performed up to twice per year, allowing customers to schedule the patching at their convenience. The patching is usually done to keep the software and firmware up-to-date and to fix any known security vulnerabilities. It's important to note that patching services are not done automatically during business hours, customer's involvement and schedule is needed, and the rolling and complete downtime approaches are options to minimize the impact on the system during patching.

The correct statement about the patching features provided in Platinum Services is that patching services are available for the full software stack up to twice per year. Oracle Platinum Service covers Exadata storage software and firmware patching, and customers must also perform the database patching. The rolling and complete down time approaches are two options for patching, and patching should be scheduled for times when the system is not being heavily used. Patching is not done automatically during business hours. This is covered in section 4.13 of the Oracle Exadata Database Machine X9M Implementation Essentials Official Text Book and Resources [1].
